2.69 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent oval sapphire weighs 2.69 carats and measures 9.68 x 7.48 x 4.47 mm, exhibiting a balanced table to depth ratio that yields approximately 52 percent depth, an optimal proportion for live brilliance and controlled windowing. Cut to a mixed brilliant design, the gem pairs a brilliant crown with a modified step pavilion, producing strong face up scintillation while preserving depth of tone. Clarity is graded eye clean at standard viewing distances, allowing unobstructed light transmission to emphasize the stone geometry, and polish is excellent, producing crisp facet junctions and sharp light return. Color intensity is classified as intense, with heat enhancement applied to stabilize and deepen the blue hue, a common and accepted treatment that enhances saturation without obscuring natural zoning. The finish and proportions are tailored for everyday wear in a fine jewelry setting, and The Natural Sapphire Company confirms Sri Lankan origin, a provenance that correlates with the gemology observed.

Comparatively, the hue and tone of this Ceylon sapphire lean toward a vivid pure blue with a slightly cool overtone, brighter and more lively than the classic velvety cornflower blue of Kashmir material, which typically shows a softer diffusion and a more muted, smoky medium dark tone. Against Burmese sapphires, which often present a deep royal blue with warmer undertones and greater saturation at similar sizes, this Sri Lankan example exhibits higher brilliance and a slightly lighter tone that enhances sparkle. Versus Australian and Thai stones that can appear inky and dark with strong secondary violet or green undertones, this stone reads cleaner in hue and maintains a clearer blue face up. The heat treatment intensifies the primary blue while preserving clarity, producing consistent saturation across the mixed brilliant facets, and the resulting optical performance is ideal for settings that maximize crown light dispersion. The Natural Sapphire Company recommends mounting this sapphire in a low bezel or four prong setting that allows crown light entry, to exploit the mixed brilliant cut and to showcase the distinctive Ceylon hue and lively tone when compared to other famed sapphire localities.
